The paper examines the relationship between transparency and disclosure (T&D) and firm performance in Pakistan's banking sector from 2007 to 2011, using a constructed T&D index across three subcategories. Findings indicate that overall financial performance is positively associated with T&D, excluding ownership structure disclosure, which negatively impacts firm performance. The research emphasizes the importance of enhancing corporate governance to reduce information asymmetry and improve banking sector performance in Pakistan.
